YARN-DYEING MACHINE.

SPECIFICATION forming partof Letters Patent No. 424,190, dated March 25, 1890. Application filed October 3], 1889. Serial 110.328,?89. (No model.)

To all 1077/0771, it may concern:

Be it known that I, JAMES J. FEARON, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented 5 certain Improvements in Yarn-Dyeing Machines, of which the following is a specification.

My invention consists of certain improvements in that class of yarn-dyeing machines in which the skeins of yarn are strung upon bars carried by the arms of a reel rotating within an outer casing, in the lower portion of which the dyeing-liquid is contained, so that the skeins or hanks of yarn are carried alternately through the dyeing-liquid and above the same.

One object of my invention is. to improve the devices whereby warning is given to the attendant if the yarn-carrying bars are not turned at the proper time, so as to change the position of the skeins or hanks, a further object being to insure the stoppage of the machine in the event of such failure. These objects I attain in the mannerhereinafter set 2 5 forth, reference being had to the accompanying drawings, in which- I Figure 1 is a side view of a yarirdyeing machine provided with my improvements. Fig. 2 is a perspective view of part of the machine on a larger scale. F1 3 1s a perspective View of another part of the machine, also on an enlarged scale; and Figs. 4 and 5 are respectively a longitudinal section, partly in elevation, and a sectional plan view, partly 3 5 in elevation, of part of the ske1n-guard for the reel constructed in accordance with my invention.

A represents the casing of the apparatus, to suitable bearings in which is adapted the shaft 13 of the reel, in which the yarn-carrying bars are mounted, the reel having a series of radiating arms a, to bearings in which are adapted the journals of inner and outer bars 1), free to turn in their bearings, one or both 5 of the journals of each of the outer bars having at the end a toothed disk cl, upon which acts an arm or pawl f, hung to a shaft f, adapted to a bearing in the casing A of the machine, so that as each tooth of the disk comes under the influence of the arm said disk will be turned thereby and the upper skein-carrying bar will be likewise turned, so

as to impart the desired movement to the skeins thereon. The arm f acts upon the backs of the teeth of the disk (I, which are rounded or inclined, as shown in Fig. 2; hence if from any cause a skein-carrying bar is prevented from turning the back of the tooth of the disk cl will raise the armf, and advantage is taken of this movement to sound an alarm, so that the failure of the machine to operate in the proper manner will be called to the attention of the dyer. I For this purpose I provide the outer end of the rockshaft f with an arm g, which acts upon the armh of the valve h of an air or steam whistle 71 mount-ed upon a steam or air pipe 2' at one side of the casing A, the arm g being acted upon bya spring g, the tension of which is regulated by a set-screw so that the actuating-arm f may be caused to bear upon the toothed disk cl with any desired degree of pressure, a set-screw 9 serving as a stop to limit the backward movement of the arm g, and thus restrict the approach of the arm f 75 toward the toothed disk.

Alarm apparatus intended to call the attention of the dyer to the failure of the machine to operate properly has been heretofore used on machines of this class; but a gong has been used as the alarm, and the operating devices have been so constructed that the spring for actuating the same was necessarily placed 011 the inside ofthe casing A, Where, owing to the heat and the acid liquids of the dyeingbath to which it was subjected, it soon lost its temper and became inoperative.

By constructing the alarm mechanism in accordance with my invention, the spring, being on the outside of the casing, is entirely free from these destructive influences, and hence remains permanently operative, while the whistle continues to sound the alarm until the machine receives attention, so that if there is any undue delay on the part of the attendant in looking after an improperlyopcrating machine such delay is at once manifest to the superintendent of the dyeu'oom,

Whereas the tap of" a gong is likely to pass unnoticed.

By the use of the rock-shaft f, with its in.- ternal and external arms, a steam-tight bearing in the casing for the shaft is permissible, and the internal operating arm or pawl f swings in the same vertical plane as that in which the toothed disks d travel; hence there is no lateral or side thrust upon these disks, such as would tend to bend or distort the same.

In many cases it is advisable to stop the machine when there is any failure on the part of the skein-turning device to properly operate, and for this purpose I provide the rockshaft f with an arm m, which is connected by a rod, cord, or chain m to a bell-crank le- .ver F, hung to a suitable bracket on the outside of the casing A, and connected to a retainer n for the arm G of a clutch-rod n, so that the latter will hold a clutch-sleeve p in engagement with a clutch-sleeve on one of the driving-gears s of the machine, said gear meshing into a spur-wheel s on a shaft II, which has a worm If, meshing with a Wormwheel t on the reel-shaft B.

When the skein-carrying bar 1) fails to turn and the arm f is raised by the toothed disk on said bar, the retainer 11 will be withdrawn so as to permit the arm G to move under the influence of a spring 11, and thus adjust the clutch p to a mid or. inoperative position. The driving-shaft I is also connected to the shaft H by slow-speed gears w w, which may be thrown into gear by moving the clutch 19 still farther outward, the automatic device, however, being intended simply to permit the movement of the clutch out of engagement with the high-speed gearing, so as to effect the stoppage of the machine. A belt-shifter may in some cases replace a clutch as a means of stopping the machine, and is hence regarded as its equivalent.

In order to keep the skeins within proper lateral limits on the skein-carrying bars and prevent said skeins from coming into contact with the arms of the reel, I provide each of the arms a of the reel with an inwardly-projecting stud or bracket 00, bolted to the arm at its outer end and having at the inner end a tubular socket so, into which are fitted the opposite ends of short segments of metallic tubing y, these segments extending from arm to arm and abutting against each other Within the sockets, so as to provide a metallic guardring extending completely around the reel some distance inside of the arms. By this means a permanent guard-rail, not affected by heat, moisture, or rough handling, is insured.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination of the reel and its casing, the rotatable skein-bars carried by the reel and each having a toothed disk, with an arm act-ingpn the backs of the teeth of said disk and swinging in the same vertical plane as that in which the disks move, a shaft carrying said arm and projecting through the casing, an arm on said shaft outside the casing, and a spring acting on said outer arm and serving to hold the inner arm in position for acting on the toothed disks, but permitting said arm to yield when a disk cannot turn, substantially as specified.

2. The combination of the rotating reel and its rotatable skein-bars, a yielding turning device for'said bars, a steam or air pipe having a whistle thereon, a controlling-valve on said whistle, and a lever acted on by the bar-turning device and bearing against the valve-arm, whereby it moves the latter on the forward movement, but is retracted independently of it, so as to leave the valve open, substantially as specified.

3. The combination of the rotating reel and its casing, rotatable skein-bars carried by said reel, a yielding turning device for said bars, a driving-clutch for the machine, and means whereby said clutch is released 011 the yielding of the skein-bar-turning device, substantially as specified.

l. The combination of the rotating reel and its casing, the rotatable skein-bars carried by said reel, a yielding turning device for said bars, a clutch for throwing the machine into and out of operation, a clutch-opcrating arm, a retainer therefor, and means for connecting said retainer to the yielding skeinbar-turnin g device, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES J. FEARON.
